“…Ge et al. studied the influence of PAMAM generation 2.5 on the separation and detection of heavy metal ions, by introducing a short plug of PAMAM as sweeping agent into the capillary prior to sample injection and as stationary phase in open‐tubular capillary electrochromatography. The running buffer contained 4‐(2‐pyridylazo)resorcinol as a chromogenic reagent.…”

This contribution is a methodological review of the publications about the topic from the last 2 years. Therefore, it is primarily organized according to the methods and procedures used in surveyed papers and the origin and type of sample and specification of analytes form the secondary structure. The introductory part about navigation in the architecture of stacking brings a brief characterization of the various stacking methods, with the description of mutual links to each other and important differences among them. The main body of the article brings a survey of publications organized according to main principles of stacking and then according to the origin and type of the sample. Provided that the paper cited gave explicitly the relevant data, information about the BGE(s) used, procedure, detector employed, and reached LOD and/or concentration effect is given. The papers where the procedure used is a combination of diverse fragments and parts of various stacking techniques are mentioned in a special section on combined techniques. The concluding remarks in the final part of the review evaluate present state of art and the trends of sample stacking in CE.

Recent advances in microscale separationThis review focuses on the recent advances on microscale separation technology, particularly on the new development on column and detection technologies in electrophoretic and chromatographic separation modes (i.e., CE, CEC, cLC, etc.). Representative examples illustrate also applications on the small molecules, peptides, proteins, polysaccharides, chiral and so on. 246 relevant articles are cited covering the literature published

“…In this manner, Aydoğan and coworkers have separated amino acids and nucleosides as anions by functionalizing a tentacle‐type polymer with polyethyleneimine or triethanolamine . Ge and coworkers have separated heavy metal ions on a polyamidoamine dendrimer coating surface by fast exchange with sodium ions present in the BGE solution. Guo and coworkers have separated antibiotics and inorganic anions by taking advantage of the amino groups of a nanolatex, while Zhang and coworkers have determined the same inorganic anions in ham or sausage samples using the same type of SP .…”

Open tubular CEC (OT-CEC) separates analyte mixtures by a combination of electrophoretic, electro-osmotic, and/or chromatographic effects. OT-CEC research is an active and growing field, with studies encompassing a wide range of investigations related to new strategies for chemical modification of the inner surface of the capillary, leading to the introduction of novel stationary phase coatings. This review has examined the literature on OT-CEC from 2013 to August 2015 and highlights the developments in the fabrication of highly selective stationary phases, based on materials that include cyclodextrin chiral selectors, graphene and graphene oxide, metal-organic frameworks, molecularly imprinted polymers, nanoparticles, nanolatex particles, nanocomposites, in situ generated polymers, block polymers, tentacle-type polymers, polyelectrolyte multilayers, polysaccharides, phospholipids, and proteins. This review, while considering the development of novel OT-CEC coating materials, specifically examines different immobilization or coating methodologies and approaches and also discusses the separation mechanisms that occur with these new materials. These OT-CEC coatings are intended mainly to separate low molecular weight molecules relevant to the pharmaceutical, agricultural, and food industries as well as for use in environmental monitoring.
